BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 612,27 5, dated October11, 1898.

Application filed October 19, 1897- Serial No. 655,740. (No model.)

To aZZ whom it may concern:

Be it known that 1, JOHN ROWE, of Sidney,

in the county of Fremont and State of Iowa,

have invented a new and Improved Brick- Machine, of which the followingis a full,clear,

and exact description.

The object of the invention is to provide a and without the aid ofskilled labor. I

The invention consists principally of a fixed former and anintermittently revolving presser operating over the openings in the saidformer to press the material through the latter into shape and into amold held below the former.

The invention also consists of certain parts and details andcombinations of the same, as Will be fully described hereinafter andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement on the line 11 of Fig. 2. Fig. 2 is a sectional plan view of the same on the line 2 2of Fig. 1. Fig. 3 is asimilar view of the same on the line 3 3 ofFig. 1. Fig. 4 is a like view of the same on the line 14 ofFig. 1. Fig.5 is a transverse section of the improvement on the line 5 5 of Fig. 2.Fig. 6 is a sectional plan view of the same on the line 6 6 of Fig. 1.Fig. 7 is aside elevation of part of the presser; and Fig. Sis a sideelevation of the moldboard-carrier and one of the molds, together withthe scraper for the same.

The improved brick-machine is built on a suitably-constructed frame A,supporting in its upper portion a mixing-receptacle B, containing arevoluble agitator O for stirring the material, so as to properly mixthe same previous to forming the bricks. The agitator C has a hollow hubthrough which passes loosely a driving-shaft D, set at its lower end ina suitable step in the bottom of the frame A and journaled in its upperend in a bearing in the frame A, as shown in Figs. 1 and 5.

On the upper end of the shaftD is secured a pulley D, connected by beltwith other horizontally-disposed arms of the agitator to,

pass through the material contained in the" receptacle B, for thepurpose previously mentioned. I

The lower end of the mixing vessel or re ceptacle B opens into a chamberF, formed in; the frame A, and containing a presser G, re-

ceivin g an intermittent rotary motion, as hereinafter more fullydescribed, said presser being provided with a series ofangularly-disposed wings G (see Fig. 7) for pressing the mixed materialthrough groups or sets of openings H 11 H formed in a stationary formerH, held within the frame A and practically forming the bottom of thechamber F. Below each group of openings is arranged a mold I, slidablein suitable guideways J, formed on a carrier J, receiving anintermittent rotary motion similar to the presser G, as hereinafter morefully described.

The former H, as shown in Fig. 2, has three groups or sets of openings HH H over which operate successively the wings G, the groups or sets ofopenings being disposed in such a manner that two, H 1-1 are locateddiametrically opposite each other, and with the other, H at the rear ofthe former, as plainly indicated in Fig. 2, the front of the formerbeing without a group of openings, as at this point of the machine, atthe opening A, the empty molds I are introduced and the filled molds areremoved, as hereinafter more fully described.

The first group or set of openings H at the right-hand side of themachine has each of its openings somewhat less in size than the openingsin the following set H The openings in the latter set are somewhat lessin size than the openings in the set H and the openings in the set H aresomewhat less in size than the size of the compartments in the mold Iand the finished brick. By this arrangement the sand adhering to thesides of each mold previous to its introduction into the machine is notdisturbed by the successive introduction of the clay into thecompartments of the molds, and hence the finished brick readilydischarges out of the mold after the filled mold has been removed fromthe machine and is placed upside down on the plainly indicated in Fig.6.

drying-boards in the yard. It is understood that all the molds aresanded in the usual manner before use, and the material pressed throughthe first set of openings H into the compartments of the mold occupiesbuta small space therein and does not touch the sanded sides of themold, and the material pressed through the second set of openings I-Ilikewise does not touch the sanded sides above the level of the materialintroduced, and only when the material is pressed through the third setof openings H the mold-compart- .ments become completely filled.

The openings H are closed upon starting the machine by suitable slidesK, fitted to slide in guideways in the former H, the handles of whichextend to the outside of the frame A, as is plainly indicated in thedrawlugs.

In order to impart the desired intermittent rotary motion to the presserG and the carrier J, I provide the lower end of the shaft D with agear-Wheel D formed with four sets of teeth with spaces between thesame, as is The gear-wheel D is adapted to mesh with sets of teethsuccessively with a pinion L, held on a shaft L, journaled in suitablebearings in the frame A, the said shaft carrying a gear-wheel L ,in meshwith a gear-wheel G attached to the hub G of the presser G, the said hubhaving its bore sufficiently large for the free passage of the shaft .D.The gear-wheel D is also adapted to mesh with its sets of gear-teeth,with a pinion 1.\T,secured on a vertically-disposed shaft N, j ournaledin suitable bearings on the frame A and carrying a gear-wheel N in meshwith a gear-wheel J attached to the hub of the carrier J. Now it isevident that when the shaft D and its gear-wheel D are rotated in thedirection of the arrow a (see Fig; 6) then the said gear-wheel impartsfirst a rotary motion to the pinion N, the shaft N, and the gearwheel Nto rotate the gear-wheel J 2 and the carrier J, so as to give the lattera one-quarter revolution to bring one mold I from one set of openings HH H to that of the otherand the filled mold to the opening A in theframe A for removal of the filled mold. When this has been done, anempty mold is substituted in, its place. The gear-wheel D next imparts arotary motion to the pinion L to rotate the shaft L and the gear-wheel Lto turn the gear-wheel G of the presser G, to move the wingsthereof overthe former H, and to press part of the material by the said wingsthrough the. openings in layers into the molds, as previously described.In the meantime a continuous rotary motion is given to the agitator C,so that the material is always properly kept stirred up and mixed forthe wings .to act on.

In order to assist in the removal of the filled mold through theopenings A, I provide a pusher O, fitted to slide laterally in suitablebearings A formed in the frame A. The pusher O has a lug O forengagement with a pin I on the under side of a mold, and the rear end ofsaid pusher is provided with two oppositely-arranged sets of rack-teeth0 0 adapted to be alternately engaged by a segmental gear-Wheel P,attached to the upper end of the shaft L. Thus when the latter isrotated at the time the presser G is rotated a forward-and-backwardsliding motion is given to the pusher 0, so as to push the filled mold Iforward on its bearings J to assist in the convenient removal of thesaid mold. A cover 0 secured to the frame A, extends over the pusher Oat the rack-teeth O O and the segmental gear-wheel P to protect the sameagainst sand, clay, and the like that may drop down from the mold andcarrier above.

It is expressly understood that during the time the pusher O and thepresser G are working the carrier J, with its mold, is stationary, andwhen the carrier J receives an intermittent rotary motion the presser Gand the pusher O are stationary.

Springs Q, secured to a bracket on the frame A, press with their freeends against the adjacent faces of the gear-wheels G and J to preventthe said wheels from being rotated too far by the respective gear-wheelsL and N A similar spring Q is secured to the former H and presses withits free end on the upper face of the carrier J for the same pur poseand to insure a proper register of the molds I with the openings H, Hand H A scraper I (see Fig. 8) is secured to the frame A and under itpasses the filled mold I from its last position to the opening A, sothat the bricks are properly finished on the top before the mold isremoved through the opening A.

The operation is as follows: When first starting the machine, the slidesK are closed to cover up the sets of openings H, H and H in the formerH. The mixing chamber or receptacle B is now filled with clay or othermaterial to be formed into bricks, and a rotary motion is given to theshaft D to rotate the agitator 0 within the chamber 13. At the same timethe carrier J is filled with empty molds as the guideways J come aroundto the opening A, and when the material is mixed to the properconsistency then the gates or slides K are pulled out to allow thepresserwings G to press the material through the openings of the formerinto the molds below,

IIC

as above described. At the next intermittent rotary movement a mold I,filled with clay to form finished bricks, reaches the opening A, and ispushed outward on the guideways J by the pusher O to be finally removedby the operator, who now places an empty mold on the said guideways.This empty mold is by the next intermittent movement of the.

carrier J brought to the first set of openings H- to be filled with thematerial by the corresponding wing G of the presser G.

Now it will be seen that by the arrangement described a very largenumber of bricks are continually formed in a very simple manner andwithout the aid of any skilled labor.

Having thus fully described. my invention, I claim as new and desire tosecure by Letters Patent- 1. A brick-machine providedwith a formerhaving sets of openings, of which the openings in a succeeding set arelarger than those in the preceding set, a presser operating inconjunction with the said former to press the material successively inlayers through the sets of openings into the registering compartmentsof-the-sanded molds, and means for bringing the sanded molds intoposition at the said openings of the former, substantially as described.
